Light-emitting diode

Previous peer review

I've listed this article for peer review because it seems to make little to no distinction between green vs. pure green LEDs. Green LEDs have been around since the 1970s and were introduced around the same time as orange and amber LEDs. Pure green LEDs (which are more suitable to RGB displays and traffic signals than traditional green LEDs), on the other hand, weren't introduced until the 1990s (around the same time as blue LEDs). This distinction is not only important due to the different shades of green, but the fact that they use different chemistries and have different operating voltages. I think we should include more distinction between the two different LED types, including specific wavelengths, voltages, and chemistries, as well as the histories of both types, along with appropriate sources.

As for terminology for the shades, there is also the debate on which convention to use. Some manufacturers insist on using the plain term "green" for the older style, and call the newer style "pure green" or "true green", while other manufacturers prefer to call the newer style "green" and call the older style "yellow-green" or "chartreuse".

I find it an interesting topic, however you need to cite some sources for these specifications and the controversy surrounding them. Wikipedia builds on existing published knowledge, so it is difficult to write something of this sort without sources.
